There is reason for that. Nvidia does not disclose much of chip internals (like memory layout etc), so to write decent open source driver is not possible, hence only generic functions are supported by open source nv driver. Anything a step off usual, say dual screen with different screen resolutions - quite often thing in the Department I support - is not possible. You have to install Nvidia proprietary binary driver (I often correct those who say “compile nvidia driver”. Nope! What one is compiling is interface between proprietary binary driver and specific kernel).

Same observation here. ATI chip internals were decently described by manufacturer in their documentation, so open source driver developers can write excellent drivers supporting pretty much all capabilities of the chip[set]. Such were my observations for a couple of decades, even after AMD bought ATI. Someone, correct me if you noticed things changed, which I hope they didn’t.
